The Dutchmen haven’t had quite the follow-up to their Frozen Four season last year. Union has won just once in their last eight games going 1-4-3 in that stretch. Sophomore Team USA star Shayne Gostisbehere has been part of a steady attack for the team scoring five goals with eight assists this year. If Union is going to snap out of it and start making another run for the NCAA tournament, doing damage in conference against teams like Princeton is the way to do it.

Princeton, meanwhile, are winners of two in a row beating out Ivy League rivals Harvard and Dartmouth. Back on December 1 they earned a 4-4 tie with Union in Schenectady. Now that they’re on a mini-roll and on their home ice at Hobey Baker Rink, they’re hoping to keep the good times going.

NHL prospects to watch: Union has a pair of them in Gostisbehere (Philadelphia) and freshman defenseman Tim Boyle (Ottawa). They also have solid undrafted players like Kyle Bodie, Wayne Simpson, and senior defenseman Greg Coburn, brother of Flyers blue liner Braydon Coburn. Last year’s Hobey Baker finalist Troy Grosenick still leads the way in goal.

Now they’re back into the WCHA schedule facing a Nebraska-Omaha team riding high off their weekend sweep of Colorado College last week. The Mavericks had a bit of bad news this week as Flyers prospect goalie Anthony Stolarz departed for the OHL. On the upside, recently absent goalie Ryan Massa has come back thanks to his departure.

We’re taking you “Back To Class” for our roundup of the weekend’s action in college hockey. Look for more college hockey on NBCSN this Friday night at 7:30 p.m. ET as Cornell takes on Harvard.

Did you know there’s only one unbeaten team left in the NCAA? Did you know they’re in the ECAC? Did you know it’s neither Union nor Cornell who were in the last season’s NCAA tournament? Let’s meet Dartmouth College.

The Big Green are off to a great start going 5-0-1 to start the year. Their lone blemish came thanks to a 2-2 tie against Yale in the Ivy Shootout. Since then they’ve won five straight games including a big win over Union on Saturday. How are they doing it? They’re getting huge performances in scoring and in goal from a pair of juniors.

Forward Eric Robinson already has seven goals to lead the team and tying him for first in the conference. Goaltender Cab Morris is putting up some huge numbers to start going 3-0-1 with a 1.22 goals against and a .946 save percentage and one shutout.

Add in great play from sophomore Tyler Sikura (four goals, 11 points) and Dartmouth is the early-season darling in college hockey. Coach Bob Gaudet has his team thinking big.

Gaudreaubey Baker?: BC’s Johnny Gaudreau (Calgary) continues his red hot start scoring twice against Notre Dame and adding another against BU. Expect him in the mix for the Hobey Baker Award this year and expect to keep hearing more about Boston College all year. Haters are definitely going to hate.

Butters bolts Badgers: There’s never a dull moment in Wisconsin as assistant coach Bill Butters stepped down from his job to possibly rejoin his ministry in Minnesota. Mike Eaves will be looking to fill that position as soon as possible.
